Anti-vibrating flexible and compensation joint VDJ - VDJF

The bellows prevent transmission of vibration and avoid piping length’s changes for thermal and pressure expansions, misalignment and angular movement. That function is made by a metallic bellow with two end-connections. In all bellows’ versions the material in contact with gas is stainless steel. The flanged versions are equipped with rotating flanges for an easier adapting to the piping’s counter- flanges so avoiding useless mechanical stress on the bellow.
